The Windsor is the most well-known tie knot for official occasions such as business meetings, job interviews, etc. It’s a large and symmetric knot that looks good on wide collar shirts. Keep in mind that due to its width, the Windsor visually shortens the neck a bit. The knot is rather complicated in structure and might turn out too large on thick ties, so it is recommended for lighter materials. The Duke of Windsor is commonly believed to be the inventor of the knot, but in fact it was invented by the public in an attempt to copy the large Four-in-hand knot on the Duke’s tie, which was made of especially thick materials.
